A vertebral artery dissection is a tear within the interior lining of the vertebral artery, which is positioned towards the again of the neck. It’s one among 4 main arteries that offer blood to the mind.

In the longer term, artery dissections are normally handled with a once-a-day aspirin routine. Sufferers who’ve had an arterial dissection also are prompt to keep away from the rest that reasons competitive motion of the pinnacle, together with neck manipulation, roller-coaster rides, influence sports activities or different competitive and jarring actions.
